Summary: We have reported a nickel complex that can catalyze the oxidation of ammonia to dinitrogen under ambient conditions. By using aryloxyl or N-oxyl radicals as H atom acceptors, the N-H bonds of coordinated NH3 ligands can be cleaved to generate N-2 molecules. Isotopic nitrogen studies have identified a bridging Ni-hydrazine product, supported by computational models, indicating a bimetallic homocoupling mechanism for N-N bond formation.

Summary: Catalytic methane decomposition using unsupported nickel catalysts derived from commercial nickel foam shows highly dependent catalytic performance on pre-treatment and reaction temperature. Thermal and acid-thermal treatments can greatly enhance catalytic activity, with methane conversion rates reaching up to 74.6% and 91.8% at 850 degrees Celsius. Recycling carbon deposited spent catalysts can achieve high and stable methane conversion rates, while the spent catalysts can also serve as promising candidates for supercapacitor electrode materials.

Summary: In this study, a hybrid Ni catalyst supported by CeO2 and BN was developed for efficient NH3-to-H2 conversion. The addition of BN improved the spatial distribution of Ni nanoparticles, enriched oxygen vacancies and increased Ce3+ concentration, leading to enhanced electron transfer from the support to Ni. The resulting electron-rich Ni species promoted NH3 activation and N2 desorption, ultimately boosting NH3 decomposition efficiency.

Summary: The ammonia storage characteristics of a Cu-based zeolite SCR catalyst were studied before and after shutting off the urea injection. The results show that the maximum ammonia storage decreases with the increase of exhaust temperature, and the most extended duration of ammonia storage occurs at an exhaust temperature of 220 degrees C. The NOx conversion efficiency strongly depends on the ammonia storage below 220 degrees C, while the impact of exhaust temperature gradually increases above 220 degrees C.

Summary: Magnetically insulated coaxial diodes are commonly used in high power microwave devices for generating intense annular electron beams. This study conducted electrical and optical measurements on a long-pulse magnetically insulated coaxial diode to observe the emission characteristics and plasma properties. The impact of cathode material, blade angle, diode voltage, and guiding magnetic field on the emission characteristics and plasma properties of six types of annular cathodes was investigated. The metal-dielectric cathode showed excellent emission characteristics and plasma properties, achieving impressive diode performance. Additionally, high voltage and small blade angle were found to enhance the emission capability and uniformity, while a strong magnetic field or large diode voltage reduced the axial and radial expansion velocities.

Summary: Bortezomib (BTZ) is an effective drug for multiple myeloma treatment, but it often leads to BTZ-induced peripheral neuropathy (BIPN). In this study, it was found that BTZ caused demyelination in sciatic nerves, leading to mechanical hyperalgesia and impaired nerve conduction. The mechanism was identified as the dysfunction of lysosomes and autophagy blockage in Schwann cells. However, the use of the lysosomal activator Torin1 reversed the autophagy blockage and improved the BIPN pathology.

Summary: Two-dimensional metal-organic frameworks have been widely studied due to their unique properties. However, the process of crystallization in these frameworks is not well understood. Using the microdroplet flow reaction technique, researchers were able to capture different states of Cu-BDC during crystal growth and uncover a nonclassical crystallization mechanism. The intermediate state product of Cu-BDC nanosheets showed enhanced catalytic performance due to its accessible active sites. This finding can guide the rational design of various 2D MOFs with special structures.

Summary: A facile and efficient exfoliation strategy was reported to synthesize ultrathin 2D boron and nitrogen co-doped porous carbon nanosheets (B/N-C NS) via a metal-organic framework (MOF)-derived van der Waals superstructure for electrocatalytic nitrogen reduction reaction (NRR) to synthesize NH3. The doping of boron and nitrogen can modulate the electronic structure of the adjacent carbon atoms, promoting the competitive adsorption of nitrogen and reducing the energy required for ammonia synthesis. The B/N-C NS exhibited excellent catalytic performance and stability, with a yield rate of 153.4 μg·h(-1)·mg(-1)cat and a Faraday efficiency of 33.1%, surpassing most reported NRR electrocatalysts.

Summary: Microfluidic synthesis is an advanced method for preparing metal-organic frameworks (MOFs) due to its efficiency in mass/heat transfer and controllable reaction process. However, the post-processing in most liquid-liquid methods is complicated and environmentally burdensome. This study introduces a simple and efficient air-liquid segmented flow method for synthesizing MOFs, resulting in six different MOFs with high crystallinity, yield, and homogeneous morphology compared to traditional solvothermal methods. These prepared MOFs can be applied in various fields such as gas adsorption and catalysis.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
